You can be sure that everyone in life has had the eyelid jumping time, because this situation is very common, some people will be associated with the disaster, there will be ‘left eye jumping wealth, right eye jumping disaster’, this statement spread so widely, the impact is so deep, until now, when my right eye jumping, also often feel weak in the heart. In fact, we all know that eyelid jumping can not have anything to do with wealth and disaster, so what exactly is causing eyelid jumping? In fact, eyelid jumping is medically called blepharospasm, which is caused by the involuntary contraction of the muscles inside the eyelids, and this situation is much simpler to explain from a medical and anatomical point of view. There are two types of muscles in the eyelids, one is responsible for opening the eyes and is called the levator palpebrae. The orbicularis oculi is innervated by the facial nerve, which, unlike the oculogyric nerve, emanates from the brain and then passes through the facial nerve canal and travels under the skin for some distance before innervating the orbicularis oculi. If the area behind the ear gets cold, it can lead to facial neuritis, and the swollen facial nerve can be compressed by the bony facial nerve canal, which can lead to facial palsy, which is not uncommon. Mild eyelid jumping can be felt only by oneself, but not by others. It can accumulate in the upper or lower eyelid, and it can be presumed that the stimulated area should be near the throbbing muscle at this time. This condition is often associated with exertion, lack of sleep, heavy drinking, excessive smoking, and ionic disturbances. This type of eyelid fluttering is very common and tends to stop as the influencing factors are removed, usually temporarily. In slightly more severe cases, the eyelid flutter involves the entire orbicularis oculi muscle. Since the orbicularis oculi is responsible for closing the eyes, the patient will involuntarily force the eyes to close when the eyelid flutters, and if it involves both eyes, the flutter will cause a temporary inability to see clearly, which may lead to an accident if driving. If this condition persists for a longer period of time without relief, treatment is required. The primary treatment is a local injection of botulinum toxin, which keeps the nerves from sending commands, thus relieving the muscle spasm. Since Botox is a very dangerous biological toxin, it needs to be injected in a regular large hospital to avoid serious adverse reactions. The most serious case is eyelid fluttering accompanied by muscle spasms on half of the face, which manifests as eyelid twitching along with twitching on the same side of the face and corners of the mouth; medically we call this condition hemifacial muscle spasm. This condition involves a wide range of muscles, which means that the stimulated part is the trunk of the facial nerve. In fact, it has been confirmed that this speculation is correct, and it is now believed that the stimulated part in facial muscle spasm is the trunk of the facial nerve after it emanates from the brain, and the stimulating factor is usually vascular compression, or occasionally tumor compression. Therefore, for any patient presenting with hemifacial spasm, an MRI scan or CT scan of the head is required to rule out the possibility of a tumor. For patients presenting with facial muscle spasms, the first thing to try is medication or local injection of botulinum toxin, and if that is not effective, surgery can be considered to relieve the stimulation of the facial nerve trunk by vascular and other factors. In a sense, eyelid jumping may be an early warning of poor health, so ‘right eye jumping disaster’ may have some scientific significance, but whether ‘left eye jumping wealth’ is true only God knows.
